[Rcpp-devel] only LinkingTo: RcppEigen gives compileAttributes warning

[Dr Gregory Jefferis]

Hello,

I have package that depends on Rcpp(Eigen). Originally I imported and 
linked to Rcpp and RcppEigen. However sending the package to the 
winbuilder server, r-devel complains that I only need to link to 
RcppEigen:

* checking package dependencies ... NOTE
Package in Depends/Imports which should probably only be in LinkingTo: 
'RcppEigen'

But removing RcppEigen from the Imports field gives me the Rcpp warning:

Warning message:
The following packages are referenced using Rcpp::depends attributes 
however are not listed in the Depends, Imports orLinkingTo fields of the 
package DESCRIPTION file: RcppEigen

Now I would certainly choose an Rcpp warning over a CRAN note any day of 
the week, but is this actually an issue? Furthermore it seems to me that 
the compileAttributes warning is spurious – RcppEigen **is** listed in 
LinkingTo.

I have seen this question on the mailing list:

http://comments.gmane.org/gmane.comp.lang.r.rcpp/7181

where the same warning was a side issue and dismissed as irrelevant and 
harmless. In any case, clarification would be welcome.

Many thanks,

Greg.
